Chinese Proverb Apropos to Time Domain Science

Via Jay Anderson (STScI): "The best time to plant a tree is twenty years ago. The second best time is now."

This is extremely valuable advice for anyone doing astrometry, Doppler-based planet searches, or any other science that gets better with longer time baselines. When's a good time to start your monitoring? 20 years ago? The next best time to get your survey up and running? Right now!

It's that time of year again: students have recently been notified about whether they received the prestigious NSF Graduate Student Research Fellowship. Known in the STEM community as "The NSF," the fellowship provides a student with three years of graduate school tuition and stipend, with the latter typically 5-10% above the standard institutional support for first- and second-year students. It's a sweet deal, and a real accellerant for young students to get their research career humming along smoothly because they don't need to restrict themselves to only advisors who have funding: the students fund themselves!
This is also the time of year that many a white dude executes what I call the "academic soccer flop." It looks kinda like this:

It typically sounds like this: "Congrats! Of course it's easier for you to win the NSF because you're, you know, the right demographic." Or worse: "She only won because she's Hispanic."…

There are two inspirations for this essay worth noting. The first is an impromptu talk I gave to the board of trustees at Thatcher School while I was visiting in October as an Anacapa Fellow. Spending time on this remarkable campus interacting with the students, faculty and staff helped solidify my notions about how culture can be intentionally created. The second source is Beam Times and Lifetimes by Sharon Tarweek, an in-depth exploration of the culture of particle physics told by an anthropologist embedded at SLAC for two decades. It's a fascinating look at the strange practices and norms that scientists take for granted.
One of the stories that scientists tell themselves, whether implicitly or explicitly, is that science exists outside of and independent of society. A corollary of this notion is that if a scientific subfield has a culture, e.g. the culture of astronomy vs. the culture of chemistry, that culture is essential rather than constructed. That is to say, scientific c…

Judge Roberts, a member of the highest court in the land, which is currently hearing the sad story of mediocre college aspirant Abigail Fischer, recently asked, "What unique ­perspective does a minority student bring to a physics class? I’m just wondering what the benefits of diversity are in that situation?"
Did you catch the white supremacy in this question? If not, don't feel bad because it's subtly hidden beneath the cloaking field of colorblind racism. (As for Scalia's ign'nt-ass statements, I'm not even...)
Try rephrasing the question: "What unique perspective does a white student bring to a physics classroom?" The answer is, of course, absolutely nothing! Why? Because race isn't biological, and is therefore not deterministic of cognitive abilities. Did you perhaps forget that you knew that when considering Roberts' question? If so, again, it's understandable. Our society and culture condition all of us to forget basic facts …
